[Asterisk-Users] TE411P Really Bad Echo

I just implemented a system using a TE411P hardware echo cancellation
card.  Per Digium, I setup zaptel.conf, and zapata.conf the same way as
I always have.  To my surprise calls out to the PSTN had a terrible
echo. 1 - 2 second delay, and quite clear.  The echo was so bad that I
had to remove the hardware echo cancellation module from the card.  We
are only using the 1st span of this card right now, and we have a
tdm400p with 4 fxs modules installed as well.

If anyone has experience with this card, can you tell me if I am missing
something.

1 to 2 _seconds_? There is no echo canceler anywhere that will handle 
that much echo delay.

Did you actually remove the VPM, or just disable it? Please check 
whether you have this problem with the VPM installed but disabled, 
because it could be a bad VPM.

Finally... I know it's Sunday night, but you should really pursue this 
with Digium Support tomorrow morning :-)

1 to 2 seconds?!  That's ridiculously huge.  I don't think you'll
find
a echo canceler anywhere that can fix your echo problem.  If it gets 
better with the VPM disabled, then definitely contact Digium 
tech-support about it.

[Asterisk-Users] TE411P Really Bad Echo

Try Sangoma, I believe you can try it and return it within 30 days for a
full refund.

Stagg - I know you get a full 128ms tail of echo can on the Sangoma.  I
believe that on the TE411P, the 128ms tail is shared by all (4) spans,
and as you add additional spans up to maximum of 4, the echo can tail
amount decreases accordingly.  If you are running 4 spans, you have 32ms
of echo can tail on each span, not the full 128ms.

 

Now that I'm reading back through your post thread, it looks like you
were only running 1 span on the TE411P, so you should have been getting
the full 128ms of echo can tail.  You may not find an improvement with
the Sangoma.  I have never experience, nor heard of a 1-2 full second
delay.  Trial and error is likely your course of action.

	It was Digium's opinion that perhaps the card had a VPM.  We got
a replacement TE411P, I implemented it tonight and still the exact same
echo problem.  At this point I feel like I can rule out failed hardware.

	
	I contacted Digium support and now they are telling me it's
something with my carrier, and I should call them.  I called Bellsouth,
and they ran a full stress test on the circuit taking me offline for
about 30 minutes.  
	
	The end result is that the circuit test passed with no errors.
Bellsouth says it's not in their network, Digium says its not their
card, and I have a te411p with VPM disabled in the wct4xx kernel module
because something doesn't work the way it should.  My customer is
wanting to know about sangoma cards with the echo cancellation, and at
this point I'm nervous to recommend any hardware.  I'm going to look
into the sangoma that you suggested.  Are there any other kinds of
products that I could look into either Passive or Active.

[Asterisk-Users] TE411P Really Bad Echo

I thought that if the VPM was detected then you didn't have any control as
to which algorithm was used.

I was under the impression that the algorithms were only used for the software
echo cancellation.

At this point I'll give anything a try.

I don't think it's a matter of trying echocancel on and off, it is a
matter
of tuning your system to your local PSTN - this is a combination of trying
the different echocan alogrithims (i.e. MG2), the echotrainign etc and
setting your txgain - too loud outgoing audio will result in echo.

[Asterisk-Users] TE411P Really Bad Echo

I can definitely vouch for Sangoma?s cards with hardware echo
cancel.  I?ve been installing Asterisk boxes for about 6
months now using Digium TDM cards and Sipura SPA-3000s in
small installations.  This past month I installed in a small
office with 3 pots lines.  The echo was very bad and of
course the phone company (SBC) claims the lines pass all
tests.  I exhausted all the echo cancel combinations in
zaptel and still had echo and bad noise during double talk. 
I installed a Sangoma A200 with hardware echo cancel and you
would never know there was a problem. It?s the best sounding
connection I?ve heard through Asterisk.

[Asterisk-Users] TE411P Really Bad Echo

WELL!

The Orion guys agreed to send me one as a demo for 30 days.  I'm doing 1
install / week now, so it was a good business opportunity for them. I had issues
with DTMF during the test phase, and the tech guys were not terribly helpful.  3
weeks into the test (a week early) collections calls me and asks why I
haven't paid yet !?!?!?!?  I fought them for another 2 weeks before I
figured out 90% of the DTMF issues, and then paid.

What version of Asterisk and Zaptel you were using? Did you try latest
Asterisk 1.2.4 and Zaptel 1.2.3? Anyone has good feedback for TE411P?

[Asterisk-Users] TE411P Really Bad Echo

Is this with the TE411P? Also what do you mean by "pulled the zaptel trunk
source"?

[Asterisk-Users] TE411P Really Bad Echo

This is with a TE411P (Digium Quad Span PRI with Voice Processing 
Module). When I say pulled the zaptel trunk source, I mean I issued the 
following command which pulled the latest available source code at that 
time:

svn checkout http://svn.digium.com/svn/zaptel/trunk zaptel

I followed up to a message previously with the exact trunk version that 
I downloaded:  SVN-trunk-r941

Sorry for the slow response, but you can get ARI here:

There are instructions for setting it up there as well.
